7.4 quake hits Japan, tsunami warning issued for 6-foot-tall wave

(SPOT.ph) A magnitude-7.4 earthquake aftershock hit Japan yesterday, about a month after the country was struck by a magnitude-8.9 quake which triggered a tsunami that flattened the northeastern coast and sparked explosions in a nuclear power plant, reports the AP.

According to the report, a tsunami warning for a wave of up to six feet was issued in the coastal area. The aftershock yesterday hit 40 kilometers under the water and off the coast of Miyagi prefecture.

The AP reports that there was no heavy damage to the buildings that shook violently in Ichinoseki, inland from the eastern coast. Buildings also shook for about a minute in Tokyo.
